The World's Commodities.— 13. Silver and Copper 



5ILVKR most frequently exists in combination with other rtictals, 

 nearly half the world's output in recent years having been desilvered 

 from ores mined for other metals than silver. It is nearly always con- 

 tained in the galena lead ore, and where it occurs in its native state 

 the deposits are invariably small. The largest '■' pockets '' have been 

 found in the United state_s which with Mexico together contribute 

 nearly three-fourths of the world's supply of silver. In Mexico the 

 cliief mines lie in the Central States. In the United States Colorado 

 produces most silver, and it is also mined in Montana, Utah, Idaho, 

 Nevada, Arizona. Silver has been found in all the Australian Slates, 

 but chiefly in New south Wales, at Silverton and .Broken Hill. 

 In Canatia, Cobalt has become an important silver mining district. 



COPPiiR is widely distributed, but for the last fifty years the 

 United States has been the chief producer. Great Britain now pro- 

 duces littl^^ but the smelting of the ore from all parts of the 



world is carried on, chiefly at Swansea, In tho United stales. 

 Montana, with about one-third of the country's output, Michigan, 

 with more than one-fourth, Arizona, Utah, California and Colorado 

 are the chief copper bearing regions. In Mexico the cliief mines are 

 those of Boleo in Lower California, and Cananca in Sonora. Chife 

 is stili rich in copper, though the industry has declined, and it is 

 extensively mined in the Corocoro district of Bolivia. In Australia, 

 copper forms the most important mineral raised in Tasmania and 

 South Australia, and it is also raised in Western Australia, Queens- 

 land, and New South Wales. British Columbia is the richest copper 

 province of Canada. Namaqua Land is the only copper district of 

 Cape Colony, but copper mining is :being developed in Rhodesia. 

 The diagram shows 1905-6 values, abnormal values prevaihng in 

 1906-7, when standard copper reached £109^ per ton, compared with 

 £81, an increase of 35 per cent.
